What is hyperlink?
Hyperlink or often just “Link” is the designation for a reference within a hypertext document to another document. The document that is being “linked” does not necessarily have to be a website; it can also be a link to a media file, such as an image or video. In principle, any document type can be linked as long as it has a unique address.
On the Internet, links are usually made to websites, media content or .pdf documents. Linking between different documents is one of the basic functions of the Internet. This means that content no longer has to be received linearly, but can be linked to one another through references. In the HTML code, a link looks like this:
<a href=” https://elinksbox.xyz/”> Example text </a>
The code thus contains the hyperlink target and the link text. This is the text that will ultimately become clickable. Clicking on “Example Text” would lead to the website www.beispielwebsite.de with the code above.
Links have a linear structure when you get from one web content to the next without this web content being linked to one another via navigation or the like. Link lists or PDF documents typically have a linear structure. With the network structure, the user can go from every linked page to every other linked page – a classic structure for menus and online shops.
For example, if the user clicks on the “Furniture” category in a shop, he can still go straight to any other category, since all other categories remain visible when the “Furniture” category is called up. The tree structure has the property that the user can go deeper into the page with one click and further links can then be opened.
The tree structure can also be related to the categories of online shops: Categories often still have sub-categories that are only visible once the main category has been selected. Wikis, on the other hand, typically have a star structure. This is characterized by the fact that subpages are linked to one another without having a common superordinate category (because then it would be a tree structure).
There are different types of links, the differences of which are particularly relevant for search engine optimization. For example, a distinction is made between internal links and external links or backlinks. Internal links are references to other content within the site. On a news website, for example, this would be links between different articles. Internal links can be structured differently. Typical link structures are explained below.
The backlinks or external links, however, are links that refer to your own website from other websites. The so-called backlink structure or link building is one of the basic tasks of search engine optimizers. In addition, links from social networks are referred to as social signals , links from particularly trustworthy sites (for example from a reputable news site) as trust links, links that are tagged with “nofollow” as nofollow links and deep links are links to deeper in the Content lying on the page structure. These link types can also overlap.
In principle, every link can be provided with a nofollow tag, which ensures that the search engine’s crawler does not follow the link.
A permalink is the opposite of a dynamic link. A permalink is when web content has a unique URL that is persistent. Hence the name: Permalink is the common name for a “permanent link”. Permanent links ensure that links do not become “dead” links. References with dead links do not work. Nowadays, most content management systems work with permalinks, because it makes sense in every respect that hyperlinks work permanently. Permalinks are particularly beneficial for search engine optimization.
The relevance of hyperlinks for search engine optimization
Hyperlinks are critical to search engine optimization. The Google search is based on the page rank of Google founder Larry Page. This made the number of links the decisive criterion when evaluating a website by the search engine. Although the criteria have changed a lot since Google was founded – today it is less the number than the quality of links that counts – nonetheless, building backlinks is still one of the basic tasks of search engine optimizers.
